SLANT RESILIENT VEHICLE-WHEEL.

T all whom 'it 'may concern:

Be it known that I, HERBERT G. dif- KINNEY, a citizen of the United States ot America, and a resident ol' Providence, in

Island7 have invented certain nenY and usel'ul Improvements in Resilient vehicle-Wheels,

oll which the following' is a speeitieation.

This invention relates to certain novel ini rovenients in resilient vel1icle-ivheels so called; that is to say, Wheels ol' the class in Specification of Letters Patent.

l l i l l l i which the tirewarijingr rim und the huh are connected together with a series ol' inten posed peripherally spaced sprin p spokes or ot-her analogous members rigidly secured to therim and hub, the arrangement being sueh that' when the wheels are mounted on the axles and in normal action the hubs are capable of limited independent movement in vertical planes with respect to the nonyieldingl'rinis, the degree ol said movement being determined by the weight or load in conjunction with the tension or resilieney ol the spokes. n

ln my present inwfntion the outer and inner end portions of the bent spring-spolus are inserted in correspomlinuly shaped open ings or sockets l'ormed in the rim and huh members respectively, and held in position therein by the resilieney ol the spokes themselves. r

The imgention further consists in reducing the area voll each spoke, eross-sw-.tionally, at certain points so as to increase its resiliency, and in providing the wheel with oppositely arranged parallel outer side plates adapted to l'orm auxiliary lateral supports l'or the spokes, all as more fully hereinafter set At'orth and claimed.

ln. the accompanying sheet ol' drawings, Figure l represents a l'ront .side elevation ol a resilient vehicle-wheel embodying;1 my' irn movements. Portions ol' the wheel beiner broken away to more clearlyshow the into..

longitudinally at /L or otherwise arranged to be revolublj; mounted on an axle. As

f drawn, the. thiekness ot' the center member L3 Y i is just equal to that of the steel spokes s, soon the county ot Providence and 'state ol lthoue to he desrribed. These latter, being normolly square cross-seetionally, have their me ner or lower ends s inserted and seated 1n p ripheralljf spaced rznlialnotehes a4 formed in said part a. See also Fig. l.

The annular rim portion, l, represented more. clearly in Fig'. 3, has a suitable sheetinetal .frame t, the same. beine; trough-shaped cross-sectionally and provided with outwardlyV ilnring' sides b2 lf, integral with the. rthe side o: terminates in the. inwardli' bent edge 'li'he opposite [are ol the rim has a. counterpart but removable side lange member c, iitted to the adjacent luce ol' said side b3, and having a bent unter edge c. Bolts l passingr transversely through the parts, lf2, fr ind c, serve to 'lirinly clamp the whole together. fit the base oi the said bends, o, c, is fitted and snugly held therebetween aa sheet-metal peripheral band d having its edges d bent at au angle to form an undercut spare l'or the base ofthe endless annular rubber tire .member m. Short lugs ol' studs d2 secured to or integral with the baud serre to maintain the tire in the proper normal rela-tion, thus preventing any creeping movement. The said spring-spokes e, twelve in number as drawn, are uniform in shape and size. Each has its lower end perf tion, s* inserted in the hub o, its upper or outer, end portion, s2, ,being inserted 1n an openln s formed centrally in the base part l of the slieet-iiietal trame o. A fixed collar s3, or other analogous means, continuously bearing against said base part limits the. length ofthe said inserted portion \As drawn, the body part ol the spoke, intermediate the said two end parts, is gradually reduced in thickness, as indicated si y at s4, and then bent to a coil torni e, Fig'. l; the stock being also bent laterally so that said end portions will lie in a .entrai plane. i preler to have the parts s" s2 ol` the spoke non-alining, or in other words il two radial lines be drawn extending lrom the center ol' the wheel the saine would pass through the axes ol' said parts, the'angle included between said lines not to extend bejvond the peripherj,T ol' the coil S5.
